Airships (Future Earth Chronicles Book 5)

The aliens are gone, but it’s not the end of our problems. Earth might feel a lot better, but humans still struggle.
Bel and Raj go back to North America across the Middle East and Europe where trains with steam locomotives still run and airships roam the sky. The unresponsive Rainbow Towns hide secrets Bel and Raj are not meant to discover.
A cross-continents journey with vampires, the long way home.
